如何使用 Spring 引导配置嵌入式 ActiveMQ Broker URL
How to configure embedded ActiveMQ Broker URL with Spring Boot
我遵循了一个简单的设置示例，运行 嵌入了带有 Spring 引导（版本 1.4.X）的 ActiveMQ。这是 link 示例 https://spring.io/guides/gs/messaging-jms/
我的 class 结构如下：
@SpringBootApplication
@EnableJms
public class Application {
@Autowired
ConfigurableApplicationContext context;
@Bean
JmsListenerContainerFactory<?> myJmsContainerFactory(ConnectionFactory connectionFactory) {
SimpleJmsListenerContainerFactory factory = new SimpleJmsListenerContainerFactory();
factory.setConnectionFactory(connectionFactory);
return factory;
}
@JmsListener(destination = "mailbox-destination", containerFactory = "myJmsContainerFactory")
public void receiveMessage(String message) {
System.out.println("Message received: " + message);
context.close();
}
public static void main(String[] args) throws Exception {
FileSystemUtils.deleteRecursively(new File("active-data"));
ConfigurableApplicationContext context = SpringApplication.run(Application.class, args);
JmsTemplate template = context.getBean(JmsTemplate.class);
MessageCreator messageCreator = new MessageCreator() {
public Message createMessage(Session session) throws JMSException {
return session.createTextMessage("Test");
}
};
template.send("mailbox-destination", messageCreator);
}
}
和 build.gradle 如下所示：
apply plugin: 'java'
apply plugin: 'maven'
group = 'jms.activemq'
version = '0.0.1-SNAPSHOT'
description = """jms.activemq"""
sourceCompatibility = 1.5
targetCompatibility = 1.5
repositories {
maven { url "http://repo.maven.apache.org/maven2" }
}
dependencies {
compile group: 'org.springframework.boot', name: 'spring-boot-starter-activemq', version:'1.4.0.RELEASE'
testCompile(group: 'org.springframework.boot', name: 'spring-boot-starter-test', version:'1.4.0.RELEASE') {
exclude(module: 'commons-logging')
}
}
到目前为止一切正常（只要我将 application.properties 留空），但是如果我尝试通过向 [= 添加以下内容来配置代理 url（以便远程客户端可以连接） 51=] 文件:
spring.activemq.broker-url=tcp://localhost:61616
spring.activemq.user=admin
spring.activemq.password=admin
我遇到异常：

我已经查看了一些 links，但仍然无法确定导致问题的原因。非常感谢一些见解，或者 material 可以提供帮助。
我最初的想法是 Spring Boot 将读取这些值并使用它们来配置 ActiveMQ 代理，但看起来它使用这些值连接到代理（代理已经配置了不同的设置）。如何更改代理配置，以便外部客户端（不是来自与代理相同的 JVM 的 运行）可以使用 tcp://localhost:61616
访问代理
更新：
我已经按照其中一种方法嵌入了列出的代理 here 并且能够嵌入具有所需 url 的代理并能够连接到它。但是，似乎我最终有两个代理，因为它似乎 Spring 启动仍然继续并像以前一样创建一个。
基本上，我只是在调用 SpringApplication.run(Application.class, args);
之前在 main 方法的开头添加这段代码
BrokerService broker = new BrokerService();
broker.addConnector("tcp://localhost:61617");
broker.setPersistent(false);
broker.start();
感觉一点都不对，有两个代理实例（我相信）运行。
1) 这是嵌入代理的正确方法吗
2) 如果是这样，我怎样才能阻止 Spring 引导启动另一个？ （无需删除 spring-boot-starter-activemq 依赖项）。
提前致谢。
我相信我在玩了一段时间之后就明白了。我认为有两个实例是 运行，因为我正在尝试创建与 DEFAULT 嵌入式代理的连接（试图弄清楚它是否是 created/existed），如下所示：
ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("vm://localhost?broker.persistent=false");
但显然 Spring Boot 认为一个不存在并在当时创建它。
所以为了只有我创建的实例 运行，我需要做的就是提供一个 URL 我在创建实例时添加到连接器（在本例中 tcp://localhost:61616) 在 application.properties 文件中如下
spring.activemq.broker-url=tcp://localhost:61616
和 Spring 启动将连接到此实例而不创建另一个实例。如果属性文件中没有上述条目（或者如果您尝试使用 vm://localhost 连接到嵌入式实例？...就像我上面所做的那样），Spring 引导将继续并给你实例化一个。
我也在 documentation:
上读到了这个
Spring Boot can also configure a ConnectionFactory when it detects
that ActiveMQ is available on the classpath. If the broker is present,
an embedded broker is started and configured automatically (as long as
no broker URL is specified through configuration).
但在我看来，它没有被很好地阐明（但它确实让我朝着正确的方向思考）。
如果您有不同的发现或者我的结论不正确，请务必告知。谢谢！！！
